Contract notice – general guideline, standard rule negotiated procedure with prior publication of a call for competition/negotiated procedure (services) Bad Camberg - Bayrischer Hof including annex and former toilet block, specialist structural planning Specialist structural planning for the renovation of the listed Bayrischer Hof ensemble (Strackgasse 1) ... Mehrbad Camberg - Bayrischer Hof including annex and former toilet block, specialist structural planning Specialist structural planning for the renovation of the listed Bayrischer Hof ensemble (Strackgasse 1) and the associated former toilet block, including the adjacent new building at the Bayrischer Hof Bad Camberg - Bayrischer Hof including annex and former toilet block, specialist structural planning The Bayrischer Hof is to be perceived again as the urban gateway to Bad Camberg’s old town. To this end, it is to be converted into a mixed-use development that grants the public access to the building. The ground floor is to be converted into a multifunctional room in which a tea kitchen is to be housed. Events or small concerts are to be held there in the future. Office space for the town of Bad Camberg is to be set up on the first floor and in the attic. An extension is to be planned on the northwest side of the building ("garden side"), in which an elevator and sanitary facilities are to be housed. To ensure accessibility, the elevator should be able to access all floors. As part of the planning, it must also be checked whether parking for 1-2 cars can be provided in the basement. The former toilet block is to be converted to public use. A spatial program is to be developed as part of the design planning. The cubature and roof shape are to be retained as far as possible. The possibility of opening up one side of the facade is to be examined. The town will award the other necessary planning services (building object planning, HLS and ELT) as part of further VGV (for building object planning and HLS planning) or UVGO procedures (for ELT planning). 3. Further requirements and cost framework Particular importance is attached to the following points: - Depending on the desired change of use, further planning and construction implementation must not only take into account the changed usage requirements. Current aspects of energy-saving renovation (taking into account the EEG) and fire protection, as well as the categorisation of public buildings with event space must also be included. - The increased sound insulation requirement due to the B8 must also be taken into account. - The location of the property in the funding area, an area with ensemble protection under monument protection law as well as neighbouring individual monuments and traffic-calmed areas must also be taken into account. A rough cost estimate was made for the overall renovation and partial new construction in 2024 (see Appendix B). This results in the following costs: - Total construction costs for the Bayrischer Hof and the former toilet block approx. 2.34 million euros (net, including additional costs), - Of this, approx. 2 million euros (net, including additional costs) are for the conversion/renovation of the Bayrischer Hof including the extension and - approx. 0.34 million euros (net, including additional costs) for the renovation of the former toilet block. The city of Bad Camberg intends to commission the structural planning in stages. - Stage 1: Lph 1-4 - Stage 2: Lph 5-6
